It is true that when graphically adding vectors in two dimensions, each vector arrow begins at the origin and proceeds in the direction of the vector for a distance proportional to the magnitude of the vector.
- An item with both magnitude and direction is referred to as a vector.
- A vector can be visualised geometrically as a directed line segment, with an arrow pointing in the direction and a length equal to the magnitude of the vector.
- The vector points in a direction from its tail to its head.
- The process of adding two or more vectors together to create a vector sum is known as vector addition.
